Description

LM2907 Frequency to Voltage Converter

The LM2907, LM2917 series are monolithic frequency to voltage converters with a high gain op amp/comparator designed to operate a relay, lamp, or other load when the input frequency reaches or exceeds a selected rate.

The tachometer uses a charge pump technique and offers frequency doubling for low ripple, full input protection in two versions (LM2907-8, LM2917-8) and its output swings to ground for a zero frequency input.

LM2907 frequency to voltage converter is fully compatible with the tachometer and has a floating transistor as its output. This feature allows either a ground or supply referred load of up to 50 mA. The collector may be taken above VCC up to a maximum VCE of 28V. The two basic configurations offered include an 8-pin device with a ground referenced tachometer input and an internal connection between the tachometer output and the op amp non-inverting input. This version is well suited for single speed or frequency switching or fully buffered frequency to voltage conversion applications.

Features of LM2907

Ground referenced tachometer input interfaces directly with variable reluctance magnetic pickups
Op amp/comparator has floating transistor output
50 mA sink or source to operate relays, solenoids, meters, or LEDs
Frequency doubling for low ripple
Tachometer has built-in hysteresis with either differential input or ground referenced input
Built-in zener on LM2917
±0.3% linearity typical
Ground referenced tachometer is fully protected from damage due to swings above VCC and below ground

Applications of LM2907

Over/under speed sensing
Frequency to voltage conversion (tachometer)
Speedometers
Breaker point dwell meters
Hand-held tachometer
Speed governors
Cruise control
Automotive door lock control
Clutch control
Horn control
Touch or sound switches
